China's National Health Commission: The joint research report on the traceability of the new coronavirus is a report that can withstand the test of history

  China News Agency, Beijing, July 22 (Reporter Li Chun) Zeng Yixin, deputy director of the National Health Commission of China, said in Beijing on the 22nd that on March 30 this year, the World Health Organization officially released the global traceability study of the new crown virus convened by the WHO : The joint research report of the Chinese part, the global traceability research has made a good start.

Since the report was released, more and more scientific evidence has shown that this report is a very valuable, authoritative, scientific and historical test report.

  On the same day, the State Council Information Office of China held a press conference on the traceability of the new crown virus.

Zeng Yixin said at the meeting that at the beginning of this year, the WHO international expert group officially came to China to carry out the work of the Chinese part of the global study of virus traceability.

Upholding the principles of openness, transparency, science, and cooperation, China fully supports the work of the WHO expert group, fully meets the requirements for the visit of WHO experts, and allows WHO experts to go to all the units they want, including Jinyintan Hospital and South China Seafood Market. , Wuhan Institute of Virology and other 9 units; met all the people they wanted to meet, including medical staff, laboratory staff, scientific research staff, market managers, merchants, residents, recovered patients, and so on.

  Zeng Yixin pointed out that this traceability research report is the Chinese part of the global traceability research. The expert group has reached the following conclusion: the coronaviruses found in bats and pangolins that are most closely related to the new coronavirus are homologous to the new coronavirus in terms of sequence. The highest, but still not enough to prove that it is the direct ancestor of the new coronavirus.

  He said that combining the research results of various aspects such as clinical epidemiology, animal and environmental testing, the joint expert group finally determined several possibilities for the emergence of the virus: First, the direct spillover of zoonotic diseases is "possible to compare." may".

The second type, introduction through an intermediate host is "more likely to very likely."

The third type is the introduction through the cold chain. In some of the spreading epidemics in various places last year, it has been discovered that cold chain transmission may introduce viruses, so it is considered possible.

The last possibility is that laboratory introduction is "extremely impossible."

  Regarding the next stage of traceability work, Zeng Yixin said that, on the one hand, we are actively supporting relevant units and scientists to continue to carry out and make efforts to advance the tasks that are clearly needed in some of the reports in China, and will give feedback to the WHO in a timely manner. . On the other hand, the traceability report of the part of China has pointed out the direction for the joint traceability research of many countries and places under the global framework. (Finish)
